Title: Material-dispensing apparatus
Inventor: STRAIN FREDERICK P
IPC: B65G19/18
Filed: 1990-08-24
Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus adapted for dispensing material from an open rearward end of a container, having a wedge-shaped blade operatively coupled to an elongate endless loop, and drive means for rotation of the endless loop to allow  for back-and-forth movement of the blade within the container along a lowermost planar surface thereof.          The blade has a rearwardly-facing flat face, and a converging forward surface. In a preferred embodiment, two endless loops comprised of a plurality of chain links are provided, one at each end of the blade, each loop extending parallel to the planar surface of the container and perpendicular to the flat face of the blade. An elongate spindle member located forwardly of  the blade means is provided, extending transversely between each of the two loops.  Toothed sprocket idler wheels at opposite ends of the spindle member are provided to allow each end of the spindle member to engage the respective loops.          Alternating the direction of rotation of the endless loops causes the back-and-forth movement of the blade means along the planar surface.

Title: Process of manufacturing intermediate concrete products, form for manufacturing said products, and apparatus for carrying out said process
Inventor: KORLA JADRAN
IPC: B28B1/00
Filed: 1990-09-20
Abstract: ABSTRACT   The invention refers to a process of manufacturing intermediate concrete products, preferably tiles, which consists of casting a non-segregatable concrete mass of casting consistency into corresponding forms.  The concrete mass is cast by means of a charging head 4 and by discharge nozzles 6 arranged thereon, whereby the pressure of the concrete mass at the outlet of the nozzles 6 is adjusted to the largest cross-section of the product being cast and equals from 0.1 bar to 0.5 bar, preferably 0.2 bar.  Nozzles 6 being located in the area of the bottom of the form 5 at the beginning of casting, start to rise when the concrete mass has filled the form 5 essentially one third in height. The lifting velocity of the charging head 4 and thereby of the nozzles 6 is adjusted to the cross-section of the product being cast, and equal from 0.05 ms-1 to 0.2 ms-1, preferably 0.1 ms-1.  The invention also refers to a form for manufacturing concrete tiles and to an apparatus for carrying out said process.

Title: Process for isolating mesophase pitch
Inventor: ROMINE HUGH E
IPC: C10C3/08
Filed: 1990-09-28
Abstract: Isotropic pitch containing mesogens is combined with a solvent and subjected to dense phase or supercritical conditions and the mesogens ere phase separated. In one aspect the isotropic pitch containing mesogens is fluxed with a solvent to solubilize the mesogens, the flux mixture is filtered to remove nonsolubles and the mesogens are phase separated by use of the same solvent under dense phase or supercritical conditions of temperature and pressure. The phase separation conditions are such that the mesogens are recovered as mesophase.

Abstract: An apparatus for controlling a power supply of an electric machine in a vehicle comprises primary and secondary power supplies for supplying an electric power to the electric machine. In non-driving state of an engine, the primary power supply is selected as a power supply for the electric machine when an electric power consumption is over a predetermined value, and the secondary power supply is selected when the consumption is below the predetermined value. Therefore,  the absentee receiving of facsimile information,  the absentee recording of telephone message, etc. are carried out, even in a state of turning-off of an ignition switch. The secondary power supply is used mainly in the case that the electric machine is in waiting mode, so that the complete exhaustion of the secondary battery can be prevented.

Inventor: ENDO KAORU
IPC: H04B1/707
Filed: 1990-12-21
Abstract: The present invention provides new arrangements for various components of a CSK communication system:  modulator, correlators, demodulator, carrier detection circuit, and synchronization control circuit.  The various improvements provide more accurate demodulation of data from the received signal in the presence of noise and signal deterioration.  A modulator configuration permits the CSK system to use two M series codes in which the second code is simply a phase shifted version of the first code.  The PN correlators, via shift-registers, efficiently output two correlation signals.  The demodulator accepts two correlation signals from the correlators, detects auto-correlation peaks in the correlation signals, and uses the peaks to accurately determine whether the received bit has a value of "1" or "0".  The carrier detecting circuit detects the presence of data in the received signal.  A carrier detecting circuit conveniently allows demodulation of data without exact synchronization of the center of demodulator's monitoring window to auto-correlation peaks.  The synchronization control circuit generates accurate timing pulses that mark the start and end of each data bit.  If auto-correlation peaks appear consistently in one location for the duration of N consecutive data bits, subsequent timing pulses are delayed in accordance with weighted averages of the stored locations of auto-correlation peaks.  In one embodiment, separate correlation signal monitoring windows for demodulation and synchronization tracking may be set independently of each other, enabling the demodulator to clearly distinguish between an actual auto-correlation peaks and an inter-correlation peak, and the synchronization control circuit to attain stability by "averaging" out temporal effects of noise.

Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for the continuous measurement of the ammonia concentration in gases in the p.p.m. range comprises a columnar absorption vessel having a hemispherical plate, the plate having an overflow and an outlet.  A gas distribution tube discharges above the outlet and below a sieve plate disposed in the column.  A column packing, which fills up the absorption vessel rests on the sieve plate.  The absorption vessel extends upwardly into a cooling section, which has a cooling zone  and a gas collecting space disposed thereafter.  The space is provided with a suction inlet.  In the cooled state, a tube), whose two ends are castellated, extends from the gas collecting space downwards as far as the column packing.  The liquid absorbent is fed through a lateral inlet into the gas collecting space.  In order to carry out the measurement, a specific volume flow of the gas is washed in a counterflow with the absorbent, and the NH3 content in a portion thereof is then determined, whereupon the volume flows in the draining absorbent and of the gas that has been freed from NH3 and dried are measured and the ammonia concentration is computed.
